XIV FISHES OF ILLINOIS 



and collector of much of our material during the early years of the 

 work ; to Mr. A. J. Woolman, who, in 1903, made and recorded meas- 

 urements of many specimens of the commoner species, and who, by 

 his studies of the osteology of the Catostomidce opened the way to 

 improved generic definitions of Ictiobus and Carpiodes; and to Mrs. 

 Lydia M. (Hart) Green and Miss Charlotte M. Pinkerton, who made, 

 under the supervision of the field ichthyologists, the colored draw- 

 ings by which this report is illustrated. Professor Frank Smith, Dr. 

 C. A. Kofoid, Mr. C. A. Hart, Mr. J. E. Hallinen, and Mr. E. B. 

 Forbes have, during their several periods of service on the State Lab- 

 oratory staff, added considerably to our knowledge of the fishes of 

 the state. 



It is impracticable to give the names of all outside the staff of 

 the State Laboratory who have been, from time to time, of mate- 

 rial assistance in the long course of this work, but this list of ac- 

 knowledgments would be seriously deficient without particular men- 

 tion of Dr. S. E. Meek, of the Field Museum, and Dr. Barton W. 

 Evermann, of the U. S. Fish Commission, both of whom have been 

 especially obliging in passing judgment on sets of specimens of dif- 

 ficult determination, and in scrutinizing the tables of geographical 

 distribution printed in the introductory part of this report. It is 

 a pleasure to acknowledge also our indebtedness to a considerable 

 number of careful and observant fishermen who have told us much 

 of the habits and behavior of our best-known fishes. To Messrs. 

 John A. Shulte, of Havana, J. P. Baur, of the U. S. fisheries sta- 

 tion at Meredosia, David Yeck, of Meredosia, W. J. & H. L. Ash- 

 lock, of Alton, and Miles Newberry, of Havana, we owe many facts 

 concerning the life and economy of our fishes which we should not 

 otherwise have obtained. 



More than to any other, the Director is indebted to Mr. R. E. 

 Richardson — his colleague during three years in the preparation of 

 this report — for indispensable service in the field, the laboratory, 

 and the library, and especially for the accumulation and organiza- 

 tion of material of all descriptions, for his critical study of the col- 

 lections, all of which were finally handled by him, and for the prep- 

 aration or revision of nearly all the technical descriptions printed in 

 this volume.

Director of Laboratory
